The union representing Canadian border agents said over 90% of its members voted to go on strike as soon as June. The Wall Street Journal reported May 24 that America’s second-largest trading partner could face a possible simultaneous strike at the country’s two main railroads, Canadian National Railway and Canadian Pacific Kansas City, sometime in July. Both could disrupt billions of dollars in daily cross-border commercial trade between the U.S. and Canada.

The U.S. Department of Agriculture warned the border agent strike could have “significant impacts” for agriculture trade, producers and consumers. 

The Public Service Alliance of Canada said its 9,000 members who work at the Canada Border Services Agency would be legally allowed to strike once a federal labor-board committee delivers a report recommending how the employer, the Canadian government and the union can settle differences on a new agreement.

That report could be published in early June, the union said.
